Control.Effect.Mask

Synopsis

Effects

data Mask :: Effect where Source #

An effect for masking asynchronous exceptions.

Mask is typically used as a primitive effect. If you define a Carrier that relies on a novel non-trivial monad transformer t, then you need to make a ThreadsEff t Mask instance (if possible). threadMaskViaClass can help you with that.

The following threading constraints accept Mask:

Interpretations

maskToIO :: (Carrier m, MonadMask m) => MaskToIOC m a -> m a Source #

Run a Mask effect by making use of the IO-based mask and uninterruptibleMask.

Derivs (MaskToIOC m) = Mask ': Derivs m
Prims  (MaskToIOC m) = Mask ': Prims m

ignoreMask :: Carrier m => IgnoreMaskC m a -> m a Source #

Run a Mask effect by ignoring it, providing no protection against asynchronous exceptions.

Derivs (IgnoreMaskC m) = Mask ': Derivs m
Prims  (IgnoreMaskC m) = Prims m

Threading utilities

threadMaskViaClass :: forall t m a. Monad m => (RepresentationalT t, forall b. MonadMask b => MonadMask (t b)) => (forall x. Mask m x -> m x) -> Mask (t m) a -> t m a Source #

A valid definition of threadEff for a ThreadsEff t Mask instance, given that t lifts MonadMask.

BEWARE: threadMaskViaClass is only safe if the implementation of mask and uninterruptibleMask for t m only makes use of mask and uninterruptibleMask for m, and no other methods of MonadThrow, MonadCatch, and MonadMask.

MonadMask

class MonadCatch m => MonadMask (m :: Type -> Type) #

A class for monads which provide for the ability to account for all possible exit points from a computation, and to mask asynchronous exceptions. Continuation-based monads are invalid instances of this class.

Instances should ensure that, in the following code:

fg = f `finally` g

The action g is called regardless of what occurs within f, including async exceptions. Some monads allow f to abort the computation via other effects than throwing an exception. For simplicity, we will consider aborting and throwing an exception to be two forms of "throwing an error".

If f and g both throw an error, the error thrown by fg depends on which errors we're talking about. In a monad transformer stack, the deeper layers override the effects of the inner layers; for example, ExceptT e1 (Except e2) a represents a value of type Either e2 (Either e1 a), so throwing both an e1 and an e2 will result in Left e2. If f and g both throw an error from the same layer, instances should ensure that the error from g wins.

Effects other than throwing an error are also overriden by the deeper layers. For example, StateT s Maybe a represents a value of type s -> Maybe (a, s), so if an error thrown from f causes this function to return Nothing, any changes to the state which f also performed will be erased. As a result, g will see the state as it was before f. Once g completes, f's error will be rethrown, so g' state changes will be erased as well. This is the normal interaction between effects in a monad transformer stack.

By contrast, lifted-base's version of finally always discards all of g's non-IO effects, and g never sees any of f's non-IO effects, regardless of the layer ordering and regardless of whether f throws an error. This is not the result of interacting effects, but a consequence of MonadBaseControl's approach.
